In another embodiment, the electronic device 100 can be a wearable device capable of recording the media (e.g., audio, video, panorama image, image, etc.). The wearable device can be, for example, a smart watch, a smart bracelet, a smart glass, etc.

The electronic device 100 may include (or, be associated with) a display unit 160 (e.g., a cathode ray tube (CRT), a liquid crystal display (LCD)), a light-emitting diode (LED) being interfaced with the processor 130 (for example; a hardware unit, an apparatus, a central processing unit (CPU), a graphics processing unit (GPU)) and a recording unit 110; a storage medium 120, a region of interest (ROI) recognition unit 140, an encoder unit 150, an event detection unit 170, and a communication unit 180.

According to various embodiments of the present disclosure, an electronic device may be any combination of the foregoing devices. In addition, it will be apparent to one having ordinary skill in the art that an electronic device according to various embodiments of the present disclosure is not limited to the foregoing devices.

The recording unit 110 can be for example a video recording unit, an audio recording unit, an image recording unit, the image such as for example, panorama image, any other image, etc. The recording unit 110 can be configured to detect an event in the electronic device 100 while recording media frames on the storage medium 120. The event includes for example: a battery change event, a pause event, a memory space event, a light event and a system generated event. Further, the recording unit 110 can be configured to display a plurality of effects on a screen (i.e., display unit 160) of the electronic device 100. The plurality of effects can include for example, an animation effect, an effect to change visual parameters of at least one media frame, an effect to skip at least one media frame, an effect to secure at least one media frame, an effect to mask at least one region of interest (ROI) in at least one media frame, an effect to change a media format of at least one media frame, and an effect to switch among recording units of the electronic device 100. The visual parameters of at least one media frame may include for example brightness, resolution, blur, fade, zoom-in/zoom-out, No effect, etc. Further, changing the visual parameters of the at least one frame are explained in conjunction with the FIG. 4B and FIG. 5.

Further, the recording unit 110 can be configured to detect an effect selected from the plurality of effects displayed on the screen of the electronic device 100. The effect may be selected by the user/may be selected automatically by the processor 130. Furthermore, the recording unit 110 can be configured to apply the selected effect on at least one of at least one past media frame from a set of past media frames already recorded by the recording unit 110 and at least one future media frame from a set of future media frames to be recorded by the recording unit 110. Further, applying the selected effect on at least one of the at least one past media frame and the at least one future media frame (or the audio buffer) are explained in conjunction with FIGS. 6B-26.

The storage medium 120 includes a temporary storage medium 120 a and a permanent storage medium 120 b. The temporary storage medium 120 a can be configured to store the set of past media frames and the set of future media frames in a temporary buffer, wherein the selected effect is applied on the at least one past media frame and the at least one future media frame in the temporary buffer before storing into the permanent storage medium 120 b. The storage medium 120 may include non-volatile storage elements. Examples of such non-volatile storage elements may include magnetic hard discs, optical discs, floppy discs, flash memories, or forms of electrically programmable memories (EPROM) or electrically erasable and programmable (EEPROM) memories. In addition, the storage medium 120 may, in some examples, be considered a non-transitory storage medium. The term “non-transitory” may indicate that the storage medium is not embodied in a carrier wave or a propagated signal. However, the term “non-transitory” should not be interpreted that the storage medium 120 is non-movable. In some examples, the storage medium 120 can be configured to store larger amounts of information than the memory. In certain examples, a non-transitory storage medium may store data that can, over time, change (e.g., in Random Access Memory (RAM) or cache). The communication unit 180 communicates internally with the units and externally with networks.

In another embodiment, the recording unit 110 includes a first recording unit 110 a, a second recording unit 110 b, a media file generator 118, and sensor 112 (or sensor unit). The first recording unit 110 a can be for example, a rear camera, a primary camera, a front camera, an audio sensor, etc. the second recording unit 110 b can be for example, the rear camera, the primary camera, the front camera, the audio sensor, etc. The first recording unit 110 a can be configured to record a first set of media frames. Further, the processor 130 can be configured to detect the event, and switch the first recording unit 110 a into the second recording unit 110 b in response to detecting the event, wherein the second recording unit 110 b is configured to record a second set of media frames. The first set of media frames are recorded in a first media format and the second set of media frames are recorded in a second media format. Furthermore, the processor 130 can be configured to produce the media file comprising the first set of media frames and the second set of media frames.

Unlike conventional systems and methods, the proposed method can therefore allow the processor 130 to automatically switch the first recording unit 110 a into the second recording unit 110 b (or, vice-versa) based on the event (i.e., light event), whereby switching into the second recording unit 110 b results in improving the resolution/visual parameters of the media frame.

In yet another embodiment, the recording unit 110 can be configured to detect the event in the electronic device 100 while recording the first set of media frames in the first media format on the temporary storage medium 120 a. Further, the recording unit 110 can be configured to display a plurality of media formats on the screen of the electronic device 100. The plurality of formats can be for example, MP4, 3GP, AVI, GIF, VOB, WMV, JPEG, etc. Further, the recording unit 110 can be configured to detect a second media format selected from the plurality of media formats displayed on the screen of the electronic device 100. Further, the recording unit 110 can be configured to apply the second media format on at least one media frame from a set of second media frames to be recorded by the recording unit 110. Furthermore, the media file generator 118 can be configured to produce the media file comprising the first set of media frames in the first media format and the second set of media frames in the second media format.

Unlike the conventional systems and methods, the proposed media file generator 118 can produce a single media file including the plurality of media frames with different media formats.

The FIG. 1 shows a limited overview of the electronic device 100 but, it is to be understood that another embodiment is not limited thereto. Further, the electronic device 100 can include different units communicating among each other along with other hardware or software components. By way of illustration, both an application running on the electronic device 100 and the electronic device 100 can be the component.

FIG. 2 illustrates an architecture for performing various operations to produce a media file according to an embodiment of the present disclosure.

Referring to the FIG. 2, the recording unit 110 may include the first recording unit 110 a, the second recording unit 110 b, the sensor unit 112, a media frame management unit 114, an effect controller 116, the media file generator 118, the encoder unit 150, the temporary storage medium 120 a, and the ROI recognition unit 140.

The sensor unit 112 may include for example, an image sensor, camera circuit and modules to capture and process the media (e.g., image data, video data, audio data, etc.) outputted from the sensor unit 112. For example, the output of the sensor unit 112 may include graphics buffers containing the media content (i.e., media frames, audio buffers (or for e.g., audio tracks)), etc.).

The media frame management unit 114 may include the set of past media frames/audio buffers, the set of future media frames/audio buffer, the set of current media frames/audio buffers, etc.

The effect controller 116 may control the plurality of effects as described herein and may be configured to apply these effects. In another embodiment, the effect may also include changing the bit-rate of the at least one audio buffer, skipping the at least one audio buffer, changing the format of the at least one audio buffer, etc. Further, the effect controller 116 can be configured to apply one or more effect on the ROI preset by the user.

The display unit 160 may include for example a display panel, a display processor, a circuit, a display driver, and display interface APIs through which the graphics buffer is displayed on the display panel. While recording latest T+Nth media frame is visible on the display panel and with each queued media frame from the media content of the display panel changes.

In another embodiment, when recording is paused the T+Nth media frame is visible on the display panel due to queuing (of the media frame) the sensor unit 112 may stop recording, and the media content on the display panel remains static.

The ROI detection unit 140 may be configured to detect a preset object provided the user. The object may include for example, face in the media frame, any object of interest in the media frame, etc. The user may apply making effect/hide effect/or may skip the preset object in at least one of the past media frame from the set of the past media frames/in the at least one of the future media frame from the set of the future media frames. In another embodiment, the preset object can automatically be detected by the recording unit 110/processor 130 and may apply at least one of the aforementioned effect.

The encoder unit 150 may include for example, a video processor, a circuit, an encoder instruction module and API to process the graphics buffers through the encoder unit 150. Further, the encoder unit 150 may be configured to process raw buffers of the media frames outputted from the sensor unit 112 and encodes in specific format to store it on the permanent storage 130.

The temporary storage medium 120 a includes more than one graphics buffers to collect the media frames outputted from the sensor unit 112 and thereafter may transmit the collected media frames to the display unit 160/encoder unit 150 for preview/encoding. During the media recording (through the recording unit 110) these graphics buffers are transmitted to the encoder unit 150 to encode in specific media format and the encoder output is stored in the media file on the permanent storage medium 120 b. To apply effects on the past media frame, the media frame recorded i.e., up to the “N” number of graphics media frames may be temporary stored in the temporary storage medium 120 a and send previous than “N” media frames from 0 to T media frames to the permanent storage medium 120 b through a decoder unit (not shown).

The effect controller 116 may include a template containing the plurality of effects (or the required/selected effects from the plurality of effects) that may be applied to the graphics buffers from previous N frames. For example, if the effect required to insert between two scenes new buffer containing effect template can be queued after (T+N)th buffer. When the user resumes recording, the future media frames (from the sensor unit 112) may be queued in the “N” temporary buffers and it will be processed with the effect template selected during the pause event and is passed to the encoder unit 150.

In yet another embodiment, the recording unit 110 may include a media frame selection unit 114 configured to receive an input to select media frame (at least one past media frame from the set of past media frames) to which the user may apply the effect. Further, the recording unit 110 may include an event detection unit 170 configured to detect the at least one event and thereupon the recording unit 110 may trigger the effect controller 118 to display the plurality of effects on the display panel. The effect may be automatically applied by the processor 130.

FIG. 3 is a flow diagram 300 illustrating a method for producing a media file according to an embodiment of the present disclosure.

Referring to the FIG. 3, in step 302, the electronic device 100 detects the event while recording the media frames on the temporary storage medium 120 a. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to detect the event in the electronic device 100 while recording the media frames on the temporary storage medium 120 a.

In step 304, the electronic device 100 displays the plurality of effects on the screen of the display unit 160. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to display the plurality of effects on the screen of the display unit 160.

In step 306, the electronic device 100 detects the effect selected from the plurality of effects displayed on the screen of the display unit 160. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to detect the effect selected from the plurality of effects displayed on the screen of the display unit 160.

In step 308, the electronic device 100 applies the selected effect on at least one of the at least one past media frame from the set of past media frames already recorded by the recording unit 110 and the at least one future media frame from the set of future media frames to be recorded by the recording unit 110. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to apply the selected effect on at least one of the at least one past media frame from the set of past media frames already recorded by the recording unit 110 and the at least one future media frame from the set of future media frames to be recorded by the recording unit 110.

In step 310, the electronic device 100 produces the media file comprising the sets of the past and future media frames. For example, in the electronic device 100, as illustrated in the FIG. 1, the media file generator 110 is configured to produce the media file comprising the sets of the past and future media frames.

The various actions, acts, blocks, steps, or the like in the flow chart 300 may be performed in the order presented, in a different order or simultaneously. Further, in some embodiments, some of the actions, acts, blocks, steps, or the like may be omitted, added, modified, skipped, or the like without departing from the scope of the invention.

FIG. 4A illustrates a recording of a plurality of media frames according to a prior art.

Referring to the FIG. 4A, consider a scenario where the recording unit 110 records the media content using the sensor unit 112 and detects the pause event and thereafter detects the input to resume the recording of another scene (i.e., media frame). The recording unit 110 prepares both the scenes in the media file and the user may employ/use an external apparatus (i.e., media editing apparatus) in order to modify the media file (i.e., the media frames inside the media file) and to apply the transition effects between the two scenes.

FIG. 4B illustrates an operation for altering visual parameters of at least one media frame according to an embodiment of the present disclosure.

Unlike the conventional systems and methods as detailed in FIG. 4A, the proposed effect controller 116 (of the recording unit 110) can therefore allow the user to select the effect (change the brightness/transition effect/animation effect) while the recording is paused and apply the selected effect between two scenes without accessing/modifying previous part of the media file in the permanent storage 120 b. Thus, when the recording unit 110 detects the input to resume recording, the Dim effect selected by the user during the pause event continues to be applicable on the future media frames i.e., as shown in the FIG. 4B the next three media frames (future media frames 4-6) are slowly appearing from dark with increasing color brightness. The effect continues unless different effect is applied/till the duration of the Dim effect.

In another example, of the FIG. 4B, the proposed recording unit 110 can be used for recording family video which includes multiple pause-resume events while recording the video. The user can change, by way of the proposed effect controller 116, the visual parameters such as: dim effect for scene transition, brightness change, blur effect, etc.

In yet another example, of the FIG. 4B, during the recording of any events such as for example: convocation award functions the user records one student for collecting degree/award and then applies pause the recording to wait for a second student. If the second student is topper then the user can select, by way of the effect controller 116, the effect of glittering stars and flower/petals effects for the second student.

In further yet another example, of the FIG. 4B, the user (i.e., cook) can leverage the proposed recording unit 110 by applying a pause event, to the videos during the recording, each time when the user need to add ingredients and wait for the recipe to be ready for next ingredient. The user can select slow transition effect while pause which may produce a meaningful video content instead of direct resumed video.

Although the above illustrated example(s) are explained to apply the effect while the recording is paused but it is not limited thereto. The one or more effect to the at least one media frame can even be applied while the media is recording i.e., without any pause event.

In another embodiment, the user recording the audio buffers using audio recorder (i.e., first recording unit 110 a/second recording unit 110 b) can pause the audio recording to apply any audio effect, selected from the plurality of audio effects displayed on the display unit 160, between two audio buffers recorded between these pause events.

FIG. 5 is a flow diagram 500 illustrating a method for applying effect in middle of media recording while the media recording is paused according to embodiment of the present disclosure.

Referring to the FIG. 5, in step 502, the electronic device 100 starts recording the media frames. For example, in the electronic device 100, as illustrated in the FIG. 1, the sensor unit 112 of the recording unit 110 starts recording the media frames. During the media recording the event detection unit 170 may detect the pause event. The event detection unit 170 can be configured to detect the event automatically (system generated event) or based on the input provided by the user.

In step 504, the media management unit 114 is configured to detect an input performed by the user to select the media frame. In step 506, the effect controller 116 is configured to detect an input performed by the user to select the effect, from the plurality of effects displayed on the screen of the electronic device 100. In step 508, the recording unit 110 is configured to determine whether the selected effect is to be applied on the media frame. If at step 508, the recording unit 110 determines that the selected effect must be applied to the media frame, then, in step 510, the recording unit 110 determines, based on the input detected by the recording unit 110, whether the selected effect is to applied to the past media frame.

If at step 510, the recording unit 110 determines that the selected effect has to be applied to even the past media frame (or at least one past media frame from the set of past media frame), then in step 512, the selected effect is applied on the past media frame (i.e., past recorded graphics buffer (max “N”)). If at step 510, the recording unit 110 determines that the selected effect should not be applied to the past media frame, then in step 514, the recording unit 110 determines, based on another input detected by the recording unit 110, the effect to insert media frame, then in step 516, the recording unit 110 may create new media frames and append with the past media frames.

If at step 514, if the recording unit 110 determines that there is no input to insert media frames, then the recording unit 110 detects the input to resume the recording of the media frame. In step 518, the recording unit 110 determines whether the effect should be applied to the future media frames, if at step 518, the recording unit 110 determines that the effect is to applied event to the future media frames, then in step 522, the recording of the media frame may be resumed with the applied effect till the effect duration. If at step 518, if the recording unit 110 determines that no effect is to applied to the future media frames, then in step 520, the recording unit 110 resumes the media recording. Once the media recording is completed, then, the in step 524, the recording unit 110 stops the media recording.

If the user has recorded the first scene of video using camera for about 1 minute and paused recording to prepare for another scene. Then, the pause screen of camera application will have an option to select effects from a list. User can select from predefined effects or choose no effect. When no effect is selected then it will simply continue recording the next scene without effects. When predefined effects are selected then the effects are applied on the at least one past frame, insert effect frames (based on effect type) and apply effect on frames from next scene after recording.

As described below, the user can select previous/future/middle frames to apply effect onto. After selecting frames user can select effect to apply onto selected frames. User can select multiple effects on same media frames.

Resolution Effect:

Change the resolution of the media frame in middle of recording while the media recording is paused: FIG. 6 illustrates an operation for changing a resolution of media frames in middle of recording according to an embodiment of the present disclosure.

Referring to FIG. 6, in order to change the quality of the media frame during (or, in middle of) the pause event and resume event of the media recording, the resolution of the media frame can be changed, by way of the proposed method, before resuming the media recording assuming that the encoder unit 150 is using such a media format which supports multi resolution. Since “N” graphics buffers of fix resolution e.g. 800×1280 are in the temporary storage medium 120 a, these “N” graphics buffers may be flushed to the encoder unit 150 to store on the permanent storage medium 120 b and the temporary buffers will be deleted/marked to be deleted. Thus, the recording unit 110 with low resolution e.g. 480×800 buffers can be allocated to record the media frames after resuming the media recording. The configuration of the sensor unit 112 and the encoder unit 150 may be updated according to the new resolution (i.e., 480×800) and the user can resume the media recording with the new resolution.

FIG. 7 is a flow diagram 700 illustrating a method for changing a resolution of at least one media frame according to embodiment of the present disclosure.

Referring to the FIG. 7, in step 702, the electronic device 100 starts recording the media frames. For example, in the electronic device 100, as illustrated in the FIG. 1, the sensor unit 112 of the recording unit 110 starts recording the media frames. During the media recording the event detection unit 170 may detect the pause event. The event detection unit 170 can be configured to detect the event automatically (system generated event) or an input provided by the user.

Once the pause event is detected, in step 704, the electronic device 100 displays the plurality of effects i.e., the plurality of visual parameters (i.e., resolution effect). For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to communicate with the display unit 160 to display the plurality of effects.

In step 706, the electronic device 100 determines whether the instructions/input to change the resolution of the at least one media frame is received. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to determine whether the instructions/input to change the resolution of the at least one media frame is received.

If at step 706, the electronic device 100 receives the instructions to change the resolution of the at least one media frame, then, in step 708, the electronic device 100 flushes “N” recorded media frames to the encoder unit 150. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to flush N″ recorded media frames to the encoder unit 150.

In step 710, the electronic device 100 deletes/mark “N” temporary graphics buffer of the media frame including the old resolution effect. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to deletes/mark “N” temporary graphics buffer of the media frame including the old resolution effect.

In step 712, the electronic device 100 creates new “N” temporary graphics buffer of the media frame including the new resolution effect (selected/required). For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to create the new “N” temporary graphics buffer of the media frame including the new resolution effect (selected/required).

In step 714, the electronic device 100 updates the sensor unit 112 (i.e., camera module) and the encoder unit 150 compatible information. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 is configured to update the sensor unit 112 (i.e., camera module) and the encoder unit 150 compatible information.

If at step 706, the electronic device 100 determines that there are no instructions/input detected (by the processor 130/recording unit 110) then, the user resumes the media recording (by providing an input to the resume record button). In step 716, the electronic device 100 resumes the media recording. Once the media recording is completed, then, the in step 718, the electronic device 100 stops the media recording.

FIG. 8 illustrates an operation for skipping at least one media frame according to an embodiment of the present disclosure.

Referring to the FIG. 8, once the recording unit 110 receives the input to: stop the recording of the media frame and to mark/delete/skip the media frame, the media management unit 114 may therefore display the list of past media frames on the display unit 160, thereon, the user can select the at least one past media frame to be skipped from the media recording. Since “N” temporary buffers are in the temporary storage medium 120 a, the user can select max “N” past media frames to skip from the recording. As shown in the FIG. 8, the frames 2 and 3 are skipped, by way of the propose method, from the final set of media frames.

Further, as shown in the FIG. 8, the media frame with an obstacle in view (as seen in frame “X”) can be skipped partially (a seen in frame “Y”) or can be skipped completely (as shown in frame “Z”).

FIG. 9 is a flow diagram 900 illustrating a method for applying an effect to skip at least one past media frame according to an embodiment of the present disclosure.

Referring to the FIG. 9, in step 902, the electronic device 100 starts recording the media frames. For example, in the electronic device 100, as illustrated in the FIG. 1, the sensor unit 112 of the recording unit 110 starts recording the media frames. During the media recording the event detection unit 170 may detect the pause event. The event detection unit 170 can be configured to detect the event automatically (system generated event) or an input provided by the user.

In step 904, the recording unit 110 is configured to detect an input performed by the user to select the at least one past media frame to be skipped from the set past media frames displayed on the screen of the electronic device 100. In step 906, the recording unit 110 determines whether the at least one past media frame selected need to be skipped. If at step 906, the recording unit 110 determines that the at least one past media frame selected is to be skipped, then in step 908, the recording unit 110 skips the selected media frame from “N” graphics buffer. If at step 906, the recording unit 110 determines that the at least one past media frame selected shouldn't be skipped, then in step 910, the recording unit 110 resumes the media recording. Once the media recording is completed, then, the in step 912, the recording unit 110 stops the media recording.

FIGS. 11A-11C illustrates an operation for applying an effect during a battery change event according to an embodiment of the present disclosure.

Referring to the FIGS. 11A-11C, consider the user recording the media frame, during the media recording if the event detection unit 170 detects the battery change event (e.g., battery low) then the recording unit 110 may be configured to display at least one notification (e.g., pop-up) including the information of the current battery level (as shown in the FIG. 11B) and the plurality of effects such as, for example; plurality of resolution formats (as shown in the FIG. 11C). The user can therefore select the at least one resolution format, from the plurality of the resolution or formats, to be applied and continue the recording without any interruptions. Thus, the user by selecting the lower resolution format can resume the recording of the media (i.e., video) which explicitly prolongs the battery life and also the recording.

In the aforementioned examples and in the following examples, the one or more effect can be selected by the user/automatically selected by the processor 130/recording unit 110.

FIGS. 12A-12C illustrates an operation for skipping at least one media frame (or, audio buffer) during a disk space (i.e., memory) event according to an embodiment of the present disclosure.

Referring to the FIGS. 12A-12C, consider the user recording the media frame, during the media recording (i.e., middle of the media recording) if the recording unit 110/processor 130 detects change in the disk space (low/high) then the recording unit 110 may be configured to display at least one notification including the information of the disk space (device memory status, as shown in the FIG. 12B) and the plurality of effects such as, for example; effect, skip frames, change resolution (as shown in the FIG. 12C). The user can therefore select the at least one resolution/format/skip at least one frame from the set of past media frames in order to maintain the disk space.

FIGS. 13A-13C illustrates an operation for securing at least one media frame (or, audio buffer) according to an embodiment of the present disclosure.

Referring to the FIGS. 13A-13C, consider the user recording the media frame, during the media recording if the recording unit 110/processor 130 detects an input from the user to secure least one portion of the media frame/to add any comment on the at least one portion of the media frame. The recording unit 110 may therefore allow the user to make the at least one portion of the media frame as the private portion.

Audio Effect

FIG. 14 is a flow diagram 1400 illustrating a method for applying at least one effect to at least one audio buffer while audio recording is paused according to an embodiment of the present disclosure.

Once the recording unit 110 detects the pause event while recording the audio buffers, the display unit 160, based on the detected paused event, may display the plurality of effects to the user. The user can select from at least one effect from the plurality of effects (i.e., no color effect, skip audio buffer, change format, etc.). When no effect is selected then it will simply continue recording the next audio buffer without effects. Unlike the conventional systems and methods, the proposed method allows the recording unit 110 to apply the selected effect on the at least one past audio buffer and can apply the selected effect on the at least one future audio buffer.

In another embodiment, the plurality of effects can be pre-defined by the effect controller 116, or the plurality of effects may include a user defined effects i.e., customized by the user by combining the one or more effects from the plurality of effects.

Referring to the FIG. 14, in step 1402, the electronic device 100 starts recording the audio buffers. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 starts recording the audio buffers. During the audio (i.e., media) recording the event detection unit 170 may detect the pause event. The event detection unit 170 can be configured to detect the event automatically (system generated event) or an input provided by the user.

In step 1404, the recording unit 110 is configured to determine whether an input to select the effect to be applied on the audio buffer is detected. If at step 1404, the recording unit 110 detects the input to apply the selected effect on the audio buffer during the recording then, in step 1406, the recording unit 110 determines, based on the input detected by the recording unit 110, whether the selected effect is to applied to the past audio buffer.

If at step 1406, the recording unit 110 determines that the selected effect has to be applied to even the past audio buffer (or at least one past audio buffer from the set of past audio buffer), then in step 1408, the selected effect is applied on the past audio buffer (i.e., past recorded audio buffer (max “N”)). If at step 1406, the recording unit 110 determines that the selected effect should not be applied to the past audio buffer, then in step 1410, the recording unit 110 determines, based on another input detected by the recording unit 110, the effect to insert new audio buffer, then in step 1412, the recording unit 110 may create new audio buffer and append with previous audio buffers.

If at step 1410, the recording unit 110 determines there is no input to insert the new audio buffer, then the recording unit 110 detects the input to resume the recording of the audio buffers. In step 1414, the recording unit 110 determines whether the effect applies to the future (i.e., post) audio buffers, if at step 1414, the recording unit 110 determines that the effect is to applied to the future audio buffers, then in step 1416, the recording of the audio buffers may be resumed with the applied effect till the effect duration. If at step 1414, if the recording unit 110 determines that no effect is to applied to the future audio buffers, then in step 1418, the recording unit 110 resumes the audio recording. Once the audio recording is completed, then, the in step 1420, the recording unit 110 stops the audio recording.

For example, there are more than one audio buffers in the temporary storage medium 120 a to collect PCM data from the recording unit 110 (i.e., audio unit) and thereafter may transmit the collected PCM data to the encoder unit 150 for encoding. When recording is started these audio buffers are sent to the encoder unit 150 to encode in specific audio format and encoder output is stored in a file (i.e., media file) on the permanent storage 120 b. To apply effects on the previous audio buffers, the recording unit 110 may maintain the N number of audio buffers in the temporary storage medium 120 a and send previous than “N” audio buffers from 0 to T buffers to the permanent storage medium 120 b through the encoder unit 150. A template containing required effect will be applied to audio buffers from previous N buffers. If effect required to insert between two new audio buffer containing effect template can be queued after (T+N)th buffer. When user resumes recording the upcoming PCM data from the audio unit will be queued in N temporary buffers and it will be processed with effect template selected during pause and further it will be passed to the encoder unit 150.

The audio unit may include for example, an audio device, circuit and audio instructions to capture and process the audio data coming from the audio unit. Output of the audio unit may include audio buffers containing audio content in PCM digital format.

The encoder unit 150 may include for example an audio processor, circuit, encoder module and API to process audio buffers through the encoder unit 150. The encoder unit 150 processes raw buffers of audio buffers coming from the audio unit and encodes in specific format to store it on the permanent storage 120 b.

Change the bit rate of audio in middle of recording while audio recording is paused: FIG. 15 illustrates an operation for changing a bit rate of at least one audio buffer according to an embodiment of the present disclosure.

Referring to FIG. 15, the recording unit 110 can be configured to change the bit rate of audio buffers before resuming the recording assuming that the encoder unit 150 is using such a format which supports variable bit rate. Since “N” audio buffers in the temporary storage medium 120 a, these “N” audio buffers may be flushed to the encoder unit 150 to store on the permanent storage medium 120 b. The configuration of the audio unit and the encoder unit 150 may be updated according to new bit rate and user can resume recording with new bit rate.

FIG. 16 is a flow diagram 1600 illustrating a method for applying audio effect to change a bit rate in middle of audio recording according to embodiment of the present disclosure.

Referring to the FIG. 16, in step 1602, the electronic device 100 starts recording the audio buffers. For example, in the electronic device 100, as illustrated in the FIG. 1, the recording unit 110 starts recording the audio buffers. During the audio (i.e., media) recording the event detection unit 170 may detect the pause event. The event detection unit 170 can be configured to detect the event automatically (system generated event) or an input provided by the user.

In step 1604, the recording unit 110 is configured to detect an input to select the bitrate to be applied on the audio buffer. In step 1606, the recording unit 110 is configured to determine whether the change in the bitrate is required. If at step 1606, the recording unit 110 detects the input to change the bitrate on the audio buffer then, in step 1608, the recording unit 110 flushes “N” recorded audio buffer to the encoder unit 150. In step 1610, the recording unit 110 may update the audio unit and the encoder unit 150 compatible configuration. If at step 1606, the recording unit 110 determines that there is no change in the bitrate of the audio buffer, then in step 1612 the recording unit 110 resumes the audio recording. Once the audio recording is completed, then, in step 1614, the recording unit 110 may stop the audio recording.

FIG. 17 illustrates an operation for skipping at least one audio buffer from a set of audio buffers during recording according to an embodiment of the present disclosure.

Referring to the FIG. 17, once the recording unit 110 receives the input to: pause the recording of the audio buffer and to delete/skip the audio buffer, the display unit 160 may therefore display the audio buffer list which the user can play and make multiple selections (Mark) to skip the audio buffer from the recording.
